I NEED new graphics card and I want an ATI. I was wondering if I should buy one of the 4800 series or wait for DX11 to come out with the 5800 series. I don't want to have to spend way more than $200 and some really nice 4800s are cheap but if I wont be able to use them in a year...idk. Please help me decide. This is not a matter of what my machine can handle so I didn't bother listing specs. Thanks!
